I implemented this guide to create a flatfile from an IDoc. It works fine, but some characters are not mapped correctly: an "é" for example becomes "Ã©" and an "ú" becomes "Ãº". Is this a Unicode problem or something? If yes, how can I use Unicode in ABAP mapping?
As the XML-IDoc is transfered correctly to XI the problem is not in communication channels... it's in the ABAP mapping.
